How about defining a daemon function above,

#ifdef WIN32
static inline int
daemon (...)
{
  fprintf (stderr, "On Windows the daemon does not support forking into "
           "the background.\nYou *must* run the daemon with the -f option.\n");
  exit (EXIT_FAILURE);
}
#endif /* WIN32 */

Then you don't need any of those ugly in-function #ifdefs.
Bonus: no lines longer than 80 columns ;-)
